CFC replacements behind vast quantities of global 'forever chemical' pollution, research reveals

Chemicals brought in to help protect our ozone layer have had the unintended consequences of spreading vast quantities of a potentially toxic "forever chemical" around the globe, a new study shows. Atmospheric scientists, led by researchers at Lancaster University, have for the first time calculated that CFC replacement chemicals and anesthetics are behind around a third of a million metric tons (335,500) of a persistent forever chemical called trifluoroacetic acid (TFA) being deposited from the atmosphere across Earth's surface between the years 2000 and 2022.
